county of New have invented l Improvements in.

to improvements in toothbrushes and has for its principal object toprovide a toothbrush having a swivel head which is arrangedin such amanner as to automatically lock in such position as to permit the handleto extend from said brush head in a plane with the longitudinal axisthereof or at right angles thereto.

Therefore as another object this invention contemplates the provision ofa brush wherein it is 'possible to changethe position of the head topermit the v the brush with ease.

With these and other invention consists of a ertical movement of objectsin view the novel construction,

combination and arrangement of parts which will be fully set forth inthe following specification, claimed and illustrated in the aceompanyingdrawings in which ig. 1 is a plan View trating the handle lying head.

Fig. 2 is a view similar to the handle turned at right head.

Fig. 3 is a fragmenta brush showing portions thereof in section, to.

of the brush illusin a plane with the Fig. 1 showing angles to the ryside .view of the more clearly-illustratet-he details of theconstruction, and

Fig. 4 is a plan view of the brush head showing the handle removed.

Referring to the drawings in detail the numeral 5 designates in itsenti'retyi the brush head comprising a base 6 into which the bristles 7are secured by vulcanizing or any other suitable ,manner.

This base 6 is provided at its center with an upwardly extending pin.8which projects in a direction opposite the bristles and embedded intheupper side ofthe' base is a ring formed with sockets 9 which are"arranged as shown in Fig. 4 to hold the handle-in its various adjustedpositions. The handle previously nated by the numeral 10 referred to isdesigand is provided ad'- 1 having a jacent one end with a recess 1 forthe recentral bore 12 arranged therein 'ception of the pin 8. Embeddedin the under side of the handle and projecting from the surface thereoffor a short distance are pins 13 which areadapted to enter the sockets 9to lock the handle against accidental rotation. Seated in the recess 11is a volute spring 14.- the upper. and smaller end of so that it restsupon the spring. The pin is then slightly headed to retain the washerin. 7 place and it will be obvious that upon forcibly turning the brushhead relative to the handle, the pins 13v will enter the sockets andlock the head against accidental move ment. It will thus be seen thatthe brush I may be used inthe ordinary manner. The

head may be turned toextend transversely of the handle to facilitate thebrushing of, the teeth vertically.

While in the foregoing there has been shown and described a preferredembodiment of this invention, it is to be'understood that certain minorchanges in the details of construction may be resorted to withoutdeparting from the spirit and scope of the-'in- 8 5 vention as claimed.

What is claimed is:

1. A toothbrush having a head and ban-- dle, said handle being providedwith a per foration extending therethrough and terminating in anenlarged recess, 'a pivot pin having one end secured in said head andextending through the perforation of said handle and into said recess, adisc upon said pivot pin, a volute spring between said disc and saidhandle to urge said handle toward said head, and means between said heahandle and controlled by said spring for dand arresting the relativemovement of said head and handle at predetermined points. 2. Atoothbrush having a head and hanrecess entering from the outer surfacethereof and a perforation communicating with said recess and extendingthrough said handle, a pivot pin extending from said handle into saidenlarged recess a disk secured upon said pin, a resilient member betweensaiddisk and said handle to retain said handle closely adjacent saidhead and a plurality of pins in said handle adapted to engage in therecesses in said annular ring. 10
